AEM DryFlow was found to be the most efficient, best flow, least pressure drop, etc. Ironically, AEM is a wholly owned subsidiary of K&N.
I like the idea of a re-usable filter that you don't have to oil after cleaning, that out performs oiled filters in every aspect.
Your link was very much appreciated. Great to know.
Just may switch to aFe for the jeep as well.
Amsoil's air filters are fantastic however I think I saw something that stated they weren't going to be making them anymore which if true is a shame.
The only open element air filters worth anything are the Amsoil ones. I've got a few from various cold air intakes I came across.
The K&N filters are junk. If you look close enough you can see right through them. At best call them a flammable flame arrestor
BUT YOU KNOW WHAT... The oil in the filter is suppose to help keep dirt from flowing through.
After commenting on this thread I happened to take a looksie at the filter's dirt side and I'm glad I did. It is need of a cleaning and re-oiling.
I swapped in a fram paper I had for my replacement when the K&N needs TLC then back in she goes.
